add global detention project scraper

[HongPong]

add a scraper for the global detention project which can give more data as well as the URLs for the single sites which can be added to wikipedia stub pages, wikidata pages and so on.

There's some hint of a /search/{search query} endpoint, but I can't find any documentation.

the wordpress API is turned on but not clear if we can't find the machine name of the custom post type (assuming it works that way)

view-source:https://www.globaldetentionproject.org/wp-json/wp/v2/

it actually looks like the detention centers are not exposed in json

it looks like the whole table of american jails (way beyond ice) is here and i think it is lazy loaded but not paginated .
https://www.globaldetentionproject.org/countries/americas/united-states#detention-centres

urls seem to have a number that is probably not Wordpress post id:

• https://www.globaldetentionproject.org/countries/americas/united-states/detention-centres/2526/winn-parish-correctional-center
• https://www.globaldetentionproject.org/?p=2526 does not go to same.
